Does Debian support IDE disks with more than 128GiB or IDE 48bit addressing?
Jose Manuel dos Santos Calhariz
Hi,
I have a Samsung disk with 149GiB of space and my experience is
mixed.
What you know, or you experience with disks with more than 128GiB
working with Debian (Woody or Sarge)?
As I said my experience is mixed. The motherboard is an Asus A7V with
the last BIOS that supports 48bit addressing, have two IDE controllers
Ove VIA VT82C686/VT82C586B and the other is Promise 20265. Both of
them identify the right size (149Gib) and I can make the partitions
with fdisk or cfdisk without problems with Debian kernels 2.4.21-3-k7
and 2.4.20-3-k7 or a personalized 2.4.21 to include lmsensors, i2c,
alsa, and nvidia-kernel. I have an woody system with some packages
upgraded to sarge.
I can make a file system with more than 128GiB if connected to the VIA
controller, but connected to the Promise I will have a corrupted file
system.
- So I believe that kernel 2.4.21 with Promise don't support IDE
48bit.
- With VIA controller I have doubts, at least one time I had data
corruption. That caused me to lose the extended partition with all my
Linux file systems, more than 120GiB of data on LVM volumes.

Okay here goes:
I have a 2 - PDC 20265 based controllers in my machine. One on board,
one PCI card.
cya:~# uname -r
2.4.21-4-K7
cya:~# df

I was able to get the card to run in 2.4.19, 2.4.20 and 2.4.21. I never
tried 2.4.18. But I think it would as I have also run other distros with
older kernels.
All using the the same Motherboard as you. This machine was taken out of
service as an Engineering Workstation and re-deployed with 200GiB
Drives.
I did nothing special. Only thing I am doing is running Sid/Unstable.
